I find it curious that you lambast creationists for not reading any books about evolution before denying it. Frankly you are worse. Not only won't you read anything by Foucault or Derrida themselves, you've apparently not even read the critiques of them that you rely upon. At least creationists tend read the anti-evolution texts they advocate.
Ignorance isn't a virtue on any side.
Good for you you've found out about the Sokal's hoax. Maybe you could explain to me now what it has got to do with Foucault and Derrida? They were not writers targetted by Sokal. He criticised Lacan, Deleuze, Baudrillard and others.
